Method based on two phase distillation for utilising low temperature heat for the regeneration of CO2 solvents during CO2 capture from exhaust gases via CO2-scrubbing

摘要

Method for removing carbon dioxide from waste gases comprises using a stripping component during the regeneration of the solvent loaded with carbon dioxide. An independent claim is also included for a scrubbing installation for removing carbon dioxide from waste gases. Preferred Features: The waste gas installation comprises a heat exchanger (4) arranged between an absorber column (2) and a desorber column (6), a condenser (13) and a re-boiler (9) connected to the sump of the desorber column.
